Resumen:

The class of multivariate lq-spherical distributions is introduced and defined through their isodensity surfaces.
We prove that, under a Jeffreys' type improper prior on the scale parameter, posterior inference on the location parameters is the same for all lThe class of multivariate lq-spherical distributions is introduced and defined through their isodensity surfaces.
We prove that, under a Jeffreys' type improper prior on the scale parameter, posterior inference on the location parameters is the same for all lq-spherical sampling models with common q. This gives us perfect inference robustness with respect to any departures from the reference case of independent sampling from the exponential power distribution.[+][-]
